Title: Selection circuits for memory array
IPC: G11C8/02
Filed: 1965-02-12
Abstract: 1,070,431. Circuits of charge-atorage diodes and bi-stable magnetic elements. RADIO CORPORATION OF AMERICA. Feb. 12, 1965 [March 5, 1964], No. 6252/65. Headings H3B and H3T. Two charge-storage diodes in series opposition can exhibit three states, a current through the first diode in the forward direction storing a charge therein, a reverse current sweeping out this charge and storing it in the second diode, and a reverse current through the second diode restoring the circuit to its original uncharged state; this arrangement is used for destructive read-out and. writing in to a memory matrix, one such arrangement being associated with a word-line L 11  at each crossover point of the matrix. Normally both charge-storage diodes SDr and SDw and both ordinary diodes Ds and Dw (the latter of which may be replaced by a resistor) are back-biased and non-conductive. For read-out the appropriate read-switch RS 1  raises line y<SP>1</SP> to earth potential and the appropriate read-driver RD 1  drops line x1 to -5 volts. Current then flows from y1 to x1 via Ds and SDr storing charge in the latter. RD 1  then raises xl to + 20 volts causing the charge in SDr to be swept out into SDw, a current thus flowing through the word line L 11  changing all the cores to the ". 0 " state. Any cores that were in the " 1 state produce a signal in the appropriate line 10 leading to a sense amplifier SA. For writing-in, the write-driven W applies - 20 volts to the common bus-line z which drives out the stored charge in SDw through the wordline L 11 . Any cores that are energized by the digit-driver DD are then changed into the " 1 " state, the current being insufficient to alter the state of the other cores.

Title: Improvements relating to wire-shaping machines
IPC: B21F43/00
Filed: 1948-02-28
Abstract: 651,286. Making wire springs. HARRIS LEBUS, Ltd. Feb. 28, 1948, No. 6274. Convention date, Sept. 19, 1945. [Classes 83 (ii) and 83 (iv)]  Twisting; dies.-In a machine for bending wire furniture springs and the like, Fig. 16, from flat corrugated wire, the loops at the ends of a transverse length of the wire are located in slotted blocks which are rotated relatively to one another about an axis through the transverse length to twist the transverse length axially. The body 38 of the machine carries a shaft 45 with crank arms 47, 48 connected at their ends by a housing 50 to form a rigid unit which carries slotted blocks 59, 63 on the arm 47. A second shaft 40 freely rotates in the housing 50 and carries a crank arm 57 with an attached slotted block 58. The shafts are rotated by a vertically sliding rack 65 in the body engaging a gear sector 67 which freely rotates on the shaft 45 but is integral with a second sector 68 of larger radius which engages a pinion 54 rigidly mounted on the shaft 40. The fixed block 74 is mounted on a vertical plate 73 of a slide 72 supported by plates 71 attached to the base of the machine and is adjustable by the screw 74<SP>1</SP> to bring the transverse portions of the corrugations in line with the shaft 40, 45. The slide 72 is connected by a sliding bar 80 to an arm 81 which operates against stops 83, 84 to give a lost-motion connection to an ejector plate 77 as the slide is withdrawn to release the work. The ejector plate has a triangular opening for the arm 47 and crank 57 and is slidingly mounted in the body of the machine on rods 79 and yieldingly retracted by springs 46. A grooved block 75 attached to the plate assists in holding the wire. A spring-loaded ejector assists the plate 77. In operation the corrugated wire is clamped in the blocks 58, 59, 63 by the block 74 which is moved to the right, Fig. 6, on its slide 72 by a cam on the machine drive. The rack 65 is moved upwards by a similar cam causing the sector 68 to move in a clockwise direction, Fig. 5, carrying the arms 47, 57 in the same direction and twisting the transverse length of wire in line with the axis of the shaft 45 until a stop 69 on the arm 57  engages the side of the opening in the plate 77. The arm 57 then turns clockwise, assisted by the action of the sector 68 on the pinion 54, so twisting the transverse length of wire in line with the axis of the shaft 40, while the arm 47  continues to move until the arm 48 engages a stop 52. The slide 72 is then withdrawn to unclamp the bent spring which is then ejected by the plate 77 and ejector 85. In a simpler form of machine the wire is given a single bend by a crank similar to 47 and the second shaft 40, arm 57, and sector 68 are omitted. Both machines may be operated from a single drive and mounted on the same base at a given distance apart so that both ends of a spring may be bent simultaneously. Two such assemblies with the machines spaced at different distances apart may be used to bend a spring Fig. 16, in two operations.

Title: Method of and means for treating and purifying sewage
IPC: C02F1/68
Filed: 1933-03-02
Abstract: 415,775. Treating sewage. COOMBS, J. A., 12, Princes Park Avenue, Golders Green, London, and HEDGE, W., 213, Dartford Road, Dartford, Kent. March 2, 1933, Nos. 6349/33 and 7367/34. [Class 111.] In treating sewage by the activated sludge process, the mixed liquid and activated sludge is brought at least twice into contact with air at a free surface and at successively higher pressure, the air from the higher pressure stage being used at the lower pressure stage. The liquid may be heated at any stage. Sewage and activated sludge passing respectively over measuring weirs 13, 15, Fig. 1, mix in an open tank 11 and the mixture passes successively through closed cylindrical tanks 10. From the lowest tank 10 it passes to a settling tank 17, from which effluent liquid is discharged through a pipe 34, scum and grease through a pipe 32 and settled sludge through a pipe 19 to a closed regenerating tank 20. Air from a main 23 enters the tank 20 through diffusers 22. The air collecting above the sludge in the tank 20 is admitted to diffusers 22 in the lowest tank 10 through pipes 26 controlled by a valve 27. That collecting in the lowest tank 10 is similarly passed to the tank above and so on throughout the series. The regenerated sludge is raised by an air lift through a pipe 21 and passed to the weir 15. In the plant shown in Fig. 3 the air used passes successively through two tanks 45 containing slate or similar material, a sludge regenerating tank 42 and two treatment tanks 37. The sewage passes successively through the tanks 37 and then into a settling tank 40. Effluent from the settling- tank passes successively through the tanks 45 and is discharged to a trough 47. Sludge from the settling-tank is raised to the tank 42 and after regeneration passes to the upper tank 37. A cylindrical tank 50, Fig. 4, contains a series of inverted trays 54, 53 attached alternately to the wall of the tank and to a central flume 52. At the top of the series is a deeper tray 60 with air diffusers 61 on the top. Pipes 56, 57 deliver sewage and sludge respectively on to a deflector 55 and the mixture takes a sinuous path downwards around the trays 53, 54 contacting with air confined beneath the trays. The mixture is circulated up the flume and over a weir 58 at the top by an air lift 59 or by a centrifugal pump at the top of the flume. The mixture is withdrawn from the flume 59 through a pipe 69 delivering at an outlet 70 into a settling tank 71. Sludge from the tank 71 is raised by an air lift through a pipe 68 to the pipe 57. Pipes 63, 64 deliver air to one or more of the trays : adjacent trays may be connected by air pipes projecting under the lower tray. Diffusers may be provided above the trays. A continuous spiral may be substituted for the trays. In another modification the flow of sewage may be from side to side of a rectangular tank under trays of rectangular shape. Specification 21976/14, [Class 111], is referred to.

Title: Process for the even fluid distribution over ground surfaces
IPC: A01G25/16
Filed: 1938-03-03
Abstract: 498,574. Spray-apparatus. HORTON, A. March 3, 1938, No. 6667. [Class 69 (iii)] Liquid is evenly distributed over ground surfaces by means of piping L laid underground and provided with single spray points S arranged so that they form corners of overlapping equilateral triangles which are displaced relatively to each other a distance equal to half the side of the triangle, togetherwith a travelling spraying apparatus such as is described in Specification 253,459 adapted to be connected to the spray points in turn. The spray nozzle is rotated and as will be seen from Fig. 4, the shaded parts would be sprayed once only while the other parts are sprayed twice over. To obviate this, each circle is sprayed with only half the amount of liquid necessary so that the overlapping parts of the circles get their full amount and the rotation of the spray nozzle in passing over the shaded areas is slowed down so that an adequate amount of liquid is sprayed over these areas. Where the double shaded area shown in Fig. 5, would consequently receive too much the ring distributing device described in the above mentioned Specification is provided with additional obstructions to obviate this. The spraying nozzle is rotated both clockwise and anticlockwise and the distributing device is operated so that the liquid is sprayed in a star form, the points of which when the spraying nozzle rotates in one direction being displaced in relation to the opposite rotation of the spraying nozzle. To counteract the effect of wind the reversal of rotation of the nozzle is adjusted to take place when the spray is directed at right-angles to the wind and this may be in advance or in the rear of the nozzle in rotating. A switch device is described to effect this and as shown in Fig. 12, a rotating arm a is provided with three brushes, the centre one of which is always in contact with a conducting ring while the others are in contact with non- conducting rings provided with contacts cc, cl and these latter rings may be rotated or adjusted into required position so that a contact being made with the contacts cc or cl the required reversal takes place. A recording device may be provided to show that all the spray points have been connected with the travelling spraying device and also such other information as is desired such as the pressure &c.

The armature is then held latched by one of two pivoted latches 102, 112 which are linked so as to move outwards together under the action of a spring 106 but are eventually moved into releasing position by a rod 92 actuated by the cam 34. Specification 590,501 is referred to. The Specification as open to inspection under Sec. 91 comprises also an arrangement in which the armature 66 is held in its operated position by a retaining circuit, which is later broken by the rotation of the cam 34. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to sealing devices for relatively movable parts
Inventor: JOHNSTONE ALEXANDER PEARSE
IPC: D01D11/02
Filed: 1947-03-11
Abstract: 648,824. Stuffing-box substitutes. POWER JETS (RESEACH & DEVELOPMENT), Ltd. March 11, 1947, No. 6775. [Class 122(v)] In a sealing device to prevent excessive leakage of gas through a working clearance between the adjoining end faces of two relatively rotatable bodies, one of the end faces is formed on a movable element carried by one of the bodies and capable of movement to vary the clearance between it and the other end faces, and both end faces are provided with co-extensive flat parallel portions one of which has a multiplicity of circumferentially distributed ports therein through which, in operation, a second gas is discharged to issue in jets directed against the other flat portion so as to prevent contact of the two faces. A substantially right angled section annulus 10 acts as a movable sealing element between a gas turbine rotor 13 and casing 21 and is co-axially mounted and slidably supported on radially resilient rings 18 fitted in grooves in the casing 21, the rings making substantially gas-tight contact with the movable element 10. The radially extending arm 11 of the movable element 10 has, at its outer end, a labyrinth seal 16 which is presented to a plane face 12 of the turbine rotor 13 and, at its inner end, a plane face 17 in the same plane as the tips of the labyrinth 16 and parallel to the plane face 12. The movable element 10 and casing 21 form a chamber 22 in communication with the working gas flow to the rotor blade 28 and the pressure of that gas urges the movable element 10 towards the plane face 12 formed partly on the rotor and partly by a plate 23 attached to the rotor and having a number of small holes 24 in the part thereof, opposite the movable element. Air under pressure is supplied from the gas turbine compressor 9 through a hollow shaft 26 to the space 25 between the rotor 13 and plate 23 and issues therefrom through the holes 24 to the clearance space between plane faces 12 and 17 and contact between the movable element 10 and the rotor is thus prevented. Since the supply of compressed air is limited by the total area of the holes 24 any increase in the clearance results in a pressure drop in the clearance space between faces 12 and 17 and a consequent decrease in the clearance and vice versa so that a predetermined clearance may be maintained. If hollow turbine blades 28 are used the compressed air may be also utilized for blade cooling. In a modification the compressed air is supplied by a centrifugal compressor formed on or integral with the turbine rotor. In another modification the movable element 10 is connected by its end remote from the turbine rotor to the outer part of casing 21 by an annular flexible metallic bellows and the part 14 of the movable element and the supporting annular 15 are formed with mating splines.
